FLUID-GAGE.

Specification of Letters Patent.

Patented Slept. 24,1912.

Application led December 21, 1908. Serial No. 468,539.

llo all .whom it may concern Be it known that I, HERBERT HAs'riNos, a citizen of the United States, residing at Rochester, in' the county ot' Monroe and State of New York, have invented a new and useful Fluid-Gage, of which the following 1s a specification. My invention relates to improvements in fluid gages for constantly showing the depth or amount of' fluid in a Atank or receptacle, such for example as are commonly used for gasolene, oiland water onautomobiles, motor' boats, etc., and the objectsof my improvements are, first, t'o provide a gage that can be permanently mounted in the filler openingof tanks without changing or alteringeitlher the .o-pening or any part of the tank; second, to accomplish this lwithout interfering with the use of thisfiller opening as the `means for filling the tank; third, to provide a'filler opening cap or closure with meansfor indicating the amount of fluid. in' `thetank; fourth, to construct a' fluid gage that at the same time'may be used as the filling tube or opening of a tank and mounted in any convenient place either directly in the tank or removed from it and connected to it bya tube or pipe. These objects in the spirit of the invention, might be attained -1n a number of' `different arrangements and combinations of parts. I prefer to show however the construction illustrated in the drawing, in which` Figure l'is a partial section through the 4center in perspective showing the gage as mounted inthe filler` hole of a tank` with the cap screwed on and the top of the tank indicated as broken away. Fig. 2 is a broken perspective showing the gage attached to the filler hole collar or flange of a tank with the cap removed. Fig. 3 shows the cap removed from the gage. Fig. t shows in section the gage complete for mounting outside the tank with provision for attaching it to a pipe or tube to connect it with the tank.

Like numbers refer to like parts in the different views.

1 is the gage tube which is flanged at its upper end at la, this flange rests on top of the filler hole collar or flange 2 to which it is firmly clamped by the threaded flange collar 3 and to this collar is threaded the cap or closure 4. In the lower end of tube l is secured the bearing 5 for the lower end of the float rod 6, the upper end of' which is guided in bearing 7 which is secured near the, upper end of' said tube. The float .rod (3 may be square or rectangular n1 section with reduced cylindrical port-ions at its lower and upper ends and upon which it is free to turn under the influence of the fic-at S through the center of which the square portion of' the rod passes; as the float is caused to rise or fall by the change of' level ot the [luid in the tank, the projection 8 which engages the spiral slot,1*' in tube 1 causes the float to turn proportionately to this rise or fall and the turning motion of the float is transferred to the swivel rod (5, the upper end of" this rod is flattened at G and this portion engages the lower end of the indicator stem f) which is similarly flat'tened at 9, this stem is rotatably` and slidably mounted in the central hub ll of cap 4 and carries at its upper end the indicator pointer 10 and intermediately it has an enlarged portion or shoulder 9" against which a spiral spring 11' presses and retains it in its downward position. As cap 1l allows the indicator stem to rise in theA cap until the turning of the cap in screwing spring then forces it down in place in engagement with the float rod.

In assembling this gage in a tank it is necessary that the ["ull7 and Empty graduations of the indicator scale 12 correspond with the positions off the indicator pointer at the extreme upward and extreme downward position respectively of the float and to easily accomplish this after assembling I provide an indicator scale adjustably mounted on the cap 4 and when adjusted is held in the desired positions by screws 13.

In Fig. et the gage is shown as it' the filler hole collar or fiange 2 in Fig. 1 and Fig. 2 extended from end to end completely inclosing tube 1 and threaded at its lower end to receive the end closure '14 which is also threaded to provide a connection with the tank and also has integral wing=portions 14 as has also the upper threaded flange collar 3 'to provide means for fastening in a vertical it on brings the flats in alinement and the l position in any convenientplace with bottom of the gage level with the bottom of the tank.

I am aware that prior to my invention tluid have been made that are attached to tanks through a special opening, also that they have been made with detachable caps and that they have been made .tor mounting' exterior of the tank. l therefore do not claim the latter two combinations broadly butclaiml. ln a fluid gage a float, an indicator' controlling member actuated therebyr` a guide adapted to turn said 'float as it rises or falls, means for suspending said guide in the lillingI opening oit a tank, a removable closure for said openin'ggan indicator movably supported thereon and means for causing said indicator to automatically interengage said indicator controlling member as said closure is applied.

2. In a fluid gage a float, a collar havinga filling opening, a tloat guide supportedr thereby and adapted to turn the float as the float rises and falls, a revolving member adapted to be turned by the float, a closure for said filling opening, an indicator carried by said closure and means whereby said indicator interengages said revolving member as the closure is applied to said opening.

3. In atiuidgage the combination with a fin-id receptacle provided with a filling opening', a iioat, a float guide supported in the filling opening and provided with means for turning the float as it rises and falls, an oscillating member turned bv the float, a closure for said opening provided with an indicator and means for causing the indicator to interengage the oscillating member as the closure is applied to uthe opening.

4f. In a .tiuid gage a lioat, a body portion adapted to guide and to turn said float as it rises and falls, an open center suslriending means for said body portion, a rocking member adapted to be turned by the float, va closure for said open center, an indicator carried by the closure and means whereby the indicator always engages the rocking member in the same relation one to the other as the closure is applied.

5. In a fluid gage'a. fluid receptacle provided with a illing aperture, a pivoted member, a tioat, a guide coacting with the float to turn said pivote'd member, a repmovable closure for said aperture and means Losaeeo mounted on said closure for indicatingvthe position ot the float by contacting in one position with said pivotcd member when said closure is in position (3. in a fluid gage the con'ibinati'on with an oscillatory member, a float, a member provided with a filling opening 'and'with means coacting' with the 'floatto turn thc oscillatory member, a removable closure for said openingl and an indicator thereon provided with means for engaging the oseillatory member in al predetermined relation as the closure is placed in position.

T. ln a tluid gage a tluid holder provided with a fillingpassage, a rocking member, a tioat, lmeans 'for converting the vertical movement ot said 'tloat into angular movement of said rocking member, a closure for said passage independently removable from said rocking member and means carried by said closure 1torpositively engaging said rocking member as the closure is applied to the filling passage to indicate lthe position` of the float. l

8. ln a Huid gage a float, a guide vadapted to turn said float, means provided with a lillingbpening torrsuspending said guide, a removable cap for said opening, a shaft adapted to be turned by saidi float, an indi-v cator mounted on saidcap provided with means for engaging said shaft after disengagement as the cap is applied so that said shaft and said indicator always maintain the same position relative to each other.

i). ln a liuid gage, in combination fluid level measuring meansvwithin a receptacle provided w`th a lling opening, a removable closure for said opening provide with indicating means, and means 'for engaging said measuring means and said indicatingmeans in a predetermined relative position as the closure is applied.-

l0. In a Huid gage in combination a float,

a hollow guide adapted to impart angular movement to said float, a revoluble member adapted tobe turned by said Heat, a removable cap for said guidepindicating means carried by said cap and means acting as the cap is applied for engaging said indicating means and revoluble member in only one relative angular position. y Y
